Abstract

The invention discloses an automatic blood plasma separation meter which is provided with a plasma separating clip for clamping a blood bag, a blood bag hose clip and a hose clip control device, wherein the plasma separating clip is controlled by an extruding motor; the extruding motor is connected with an extruding motor control module; the extruding motor control module is controlled by output data of a single chip microcomputer; the single chip microcomputer is connected with a display module; the output data of a blood flowing-out detection module is connected with the single chip microcomputer; a weight detecting module and an operation key module are connected with the single chip microcomputer; a position detecting module is connected with the single chip microcomputer; and a power supply module is used for supplying power to each module. Compared with the prior art, the automatic blood plasma separation meter has the advantages of simple structure, convenience for operation and low cost, and can be used for realizing automatic blood separation, reducing artificial errors and mistakes, saving manpower resource and reducing the labor intensity.

Description

The automatic separator of blood plasma

Technical field

The invention belongs to technical field of medical instruments, be specifically related to the automatic separator of a kind of blood plasma.

Background technology

At present, the separating plasma method that each blood collection mechanism generally uses is that the blood plasma after centrifugal is placed on the plasma-separating clip, opens blood bag flow-stopping clip, and the pressure that produces with lever principle is to the pressurization of blood bag, make centrifugal after the blood plasma of layering flow in the transfering bag.When visualization blood plasma is about to flow to end, close transfering bag, will preserve the liquid flow-stopping clip simultaneously and open, the preservation flow is gone in the red cell suspension.Whole separation process needs manual observation, and speed is slow, and labour intensity is big, is prone to sneak into red blood cell in the blood plasma.External separating plasma appearance function is more, complex structure, and cost is high, the demand in incompatibility market.

Summary of the invention

For solving the problems referred to above that prior art exists, the object of the present invention is to provide a kind of simple in structure, easy to operate; With low cost, realize the separating blood automation, reduce human error and mistake; Practice thrift human resources, reduce the automatic separator of blood plasma of labour intensity.

Be to realize above-mentioned purpose, the technical scheme that the present invention adopts: the automatic separator of this blood plasma has the control device of plasma-separating clip, blood bag hose clamp and the hose clamp of clamping blood bag; It is characterized in that: said plasma-separating clip is by the extruding Electric Machine Control; Said extruding motor connects the extruding motor control module, and said extruding motor control module is exported Data Control by single-chip microcomputer, and said single-chip microcomputer connects display module; Blood flows out detection module output data and connects single-chip microcomputer; The weight detecting module connects with single-chip microcomputer with the operation push-button module, and position detecting module connects single-chip microcomputer, and power module is each module for power supply.

The control device of said hose clamp is made up of hose clamp power machine and hose clamp power machine control module, hose clamp power machine control module control connection hose clamp power machine, and hose clamp power machine control module is exported Data Control by single-chip microcomputer.

The control device of said hose clamp comprises the relay of control hose clamp folding, and relay connects single-chip microcomputer through relay circuit, is moved by the Single-chip Controlling trigger relay.

Adopt the beneficial effect of technique scheme: the automatic separator of this blood plasma has single-chip microcomputer; It is the core of whole system control; Can detect and be extruded blood and whether flow out the weight that puts, detect blood in place and flow out, detect button operation information, the information that output will show, control extruding motor and blood flow out hose pinch off motor start and stop, detect two motor action positional informations.Whether the blood that blood outflow detection module can detect in the plasma bags flows to the flexible pipe relevant position.Position detecting module can detect motor action and whether reach the qualification position.The weight detecting module can detect the weight that blood flows out.Display module can show weight and control information.The operation push-button module starts associative operation.The extruding motor control module is realized the start and stop control to the extruding motor.Hose clamp power machine control module realizes the start and stop control to the hose clamp power machine.The power supply of electric power source pair of module system.Compared with prior art, the present invention adopts electronics, machinery control, all realizes automation control; Stop artificial mistake fully; Accurately the error about blood weight to 5 gram is surveyed in control simultaneously, and maintenance cost is lower, compares with external like product; Price has absolute predominance, has wide market prospects.

Operating process

1, presses the beginning key

Push electric motor starting after pressing the beginning key, the beginning squeezes blood stops up to following 2 kinds of situation:

1) blood that squeezes out flows to flexible pipe setting place, and flexible pipe is by pinch off;

2) be expressed to the position of setting.

2, press the continuation key

Press and continue to unclamp automatically by the flexible pipe of pinch off behind the key, continue to begin extruding simultaneously and stop, simultaneously the pinch off flexible pipe up to following 2 kinds of situation:

1) the blood weight that is extruded reaches requirement;

2) be expressed to the position of qualification;

3, press end key

Press behind the end key squeezing groove and open up into that maximum goes out, the flexible pipe pinch-off device is opened, mask work finishes.

Description of drawings

Below in conjunction with accompanying drawing specific embodiment of the present invention is done further detailed explanation.

Fig. 1 is principle of the invention figure.
